Mozart composed his Adagio in B Minor, K. 540 at a time when his financial situation was steadily deteriorating. The war against the Turks was constraining the Viennese people's interest in music – works were not commissioned and concerts did not take place. It was of no matter that Mozart had shortly before (in 1787) been appointed a salaried Kammer-Kompositeur. Nevertheless, in this year he composed several of his most important works: the "Coronation Concerto" K. 537, the three late symphonies as well as several piano trios. And he also composed this tender Adagio in B Minor with its captivating expressiveness.
